Pen for Pilot G2 refill - monami style action, with clip

Pen for Pilot G2 refill

Print Instructions

Print with 0.2mm layer height, with organic support outside the pen (see the 3mf files). Print any material you would like. I recommend printing it with PETG.

Assembly Instructions

Print one pen and one endpiece. Set it together with a Pilot G2 refill and a spring.

Update:

Uploaded a better version of the endpiece (PilotG2mnm clip v10) - thinner arm + bigger protrusion = easier switch-off.

Update (02.03.2025):

Uploaded sturdier version (v13T1.8) with thicker walls (1.8 mm) and smaller hole (needs drilling/filing a little bit for the refill to fit - but then it is possible to drill/file just enough for the refill to fit snugly, so it doesn't wiggle and writing with it is more precise)

Update (10.02.2026):

Uploaded a ring for easier switching off.
